Ash Resources, the country's leading fly ash producer, was the recipient of the prestigious Construction World 2013 Best Projects Award in the Supplier category. The Award recognised the exceptional supply performance in the reliable delivery of consistent high quality classified fly ash for the construction of Medupi Power Station in Limpopo Province.
Flexibility in delivery rate and, above all, reliability of fly ash supply were paramount requirements in delivering in excess of 75 000 tons of classified fly ash to meet the project's requirement for over 650 000m³ of total concrete. The critical importance of the concrete work for Medupi and the project's tight timeline meant that it simply could not afford to run out of fly ash or have quality problems. Ash Resources supplies DuraPozz®ProTM by road from their Matla plant and is able to initiate effective back up supply arrangements from their other facilities to ensure continued supply of material at all times.
The use of Ash Resources' classified fly ash, DuraPozz® and subsequently DuraPozz®ProTM contributed to highly effective mix designs. They also featured excellent workability and ‘pumpability' which helped achieve good flow through the congested reinforcing of major concrete structures without segregation or settlement.
Ash Resources' environmentally-friendly fly ash is playing an important ‘green engineering' role in the construction of Medupi power station. It is recycling a by-product of the Eskom coal-fired power stations, as a value-added cementitious building material that improves concrete durability, prolonging the life cycle of concrete structures. The company's fly ash is also reducing process and energy output carbon dioxide (CO2) emissions associated with cement and concrete production.
Another praiseworthy feature of Ash Resources' supply performance is the fact that delivery to the Medupi project over the last five years has been without a Lost-Time Injury at the production plant or to its transport contractors. The company has demonstrated its unique capability to meet the demanding needs of customers on world-class projects for large quantities of consistent high quality classified fly ash, safely and reliably.
During the last ten years, the use of Ash Resources' fly ash by the local cement, readymix and construction industries, has saved South Africa over 15 million tons of greenhouse gas emissions.
